Increasing the activation energy results in more irregular structures characterized by stronger triple points, larger variations of the local shock velocity inside the detonation cell, and higher frequency of appearance and disappearance of triple points.
Chris Stevenson, the detective who led the investigation into the disappearance of Holly and Jessica, points out that the girls crossed Mr Huntley's path not because of his job (he worked at a different school), but because they knew his girlfriend, who had worked at their school.
For example, in [5] a detailed analysis of appearance and disappearance of paradoxical points in a continuous-time model of neural ring networks was performed.
The mixture of 2 + 3 behaves similarly, with a larger time gap between the complete disappearance of 2 (point A' in Fig. 3b) and the point at which 3 starts to self-assemble (point B' in Fig. 3b).
SEM images show clusters formation for samples with high salt concentration, and X-Ray studies point a disappearance of large peak at 2θ ≈ 20° and appearance of narrow one at 2θ ≈ 10°, confirming crystalline domains formation.
Note, the downward slope of the total mitophagy potential and the disappearance of the scatter points during the committed phase are due to the degradation of the mitochondrial population.
For the 'cued' task, an arrow appeared in place of the fixation point (i.e. in the center of the screen) for a period of 2 seconds, immediately following the disappearance of the fixation point, and correctly cued the location of the upcoming stimulus on all trials.
A delay period ensued for 500 ms, followed by the disappearance of the fixation point being the GO-signal for the memory saccade.
Both target and no-target trials ended with the simultaneous disappearance of the fixation point and placeholder boxes, and appearance of a visual feedback at fixation, 1250 to 1750 ms after the response (or after distractor display onset in no-target trials).
This was in line with physiological studies in which FEF neurons in monkeys have been shown to increase their discharge rate in response to the disappearance of the fixation point during the gap (Dias and Bruce 1994; Everling and Munoz 2000).
